Bluno - An Arduino UNO Compatible Bluetooth 4.0 (BLE) Controller

SKU: DFR0267

Bluno integrates the TI CC2540 BLE chip into an Arduino-compatible platform, providing features like wireless programming, Bluetooth HID support, and IBeacon compatibility. It requires Android 4.3+ or iOS 7.0+ devices and is not compatible with other brand BLE modules due to firmware differences. The device supports a transmission range of over 70 meters in open spaces and around 20 meters in office environments, powered via USB or external DC. With output currents of 40mA for I/O pins and 200mA for power pins, Bluno is ideal for projects requiring robust BLE communication and compatibility with Arduino Uno pin mapping.
